I have a very old cochin hen named Lula that i love quite a bit. since it is only 3 degrees here in Tonganoxie kansas i have put my chickens in the basement. Just a few minutes ago i notice Lula had some blood on her foot. She "went to the bathroom" and all it was was a cloudy white liquid. i inspected her more closely a saw that one of her back toenails has almost been completely ripped out. she is about 5 years old now and i am very worried! please help if you can! I don't know what to do.
